An update on the prevalence and management of Bertolotti's syndrome.

Bertolotti's Syndrome, a subset of lumbosacral transitional vertebrae (LSTV), is one cause of chronic low back pain (LBP), and a commonly overlooked differential diagnosis. The incidence of Bertolotti's Syndrome has been underestimated in the past and is common in those of younger ages around 30-40. Although diagnostics, imaging methods, and treatment algorithms have been improved in the past few years, there is no gold standard and more long-term, prospective research is needed. The purpose of this mini-review is to increase awareness of Bertolotti's Syndrome, discuss recent advancements in treatment algorithms, and highlight current gaps in the literature.
